Method Detail

buildRow

void buildRow(T rowValue,
              int absRowIndex)

Build zero or more table rows for the specified row value.

Parameters:

rowValue - the value for the row to render

absRowIndex - the absolute row index

finish

TableSectionBuilder finish()

Finish the building of rows and return the table section builder. Currently only HtmlTableSectionBuilder and its subclasses are supported.

getColumn

HasCell<T,?> getColumn(Cell.Context context,
                       T rowValue,
                       Element elem)

Return the column containing an element.

Parameters:

context - the context for the element

rowValue - the value for the row corresponding to the element

elem - the elm that the column contains

Returns:

the immediate column containing the element

getColumns

Collection<HasCell<T,?>> getColumns()

Return all the columns that this table builder has rendered.

getRowValueIndex

int getRowValueIndex(TableRowElement row)

Get the index of the primary row from the associated TableRowElement (an TR element).

Parameters:

row - the row element

Returns:

the row value index

getSubrowValueIndex

int getSubrowValueIndex(TableRowElement row)

Get the index of the subrow value from the associated TableRowElement (an TR element). The sub row value starts at 0 for the first row that represents a row value.

Parameters:

row - the row element

Returns:

the subrow value index, or 0 if not found

isColumn

boolean isColumn(Element elem)

Return if an element contains a cell. This may be faster to execute than #getColumn(Context, Object, Element).

Parameters:

elem - the element of interest

start

void start(boolean isRebuildingAllRows)

Start building rows. User may want to reset the internal state of the table builder (e.g., reset the internal table section builder). A flag isRebuildingAllRows is used to mark whether the builder is going to rebuild all rows. User may want to have different reset logic given this flag.

Parameters:

isRebuildingAllRows - is this start intended for rebuilding all rows
